The invention herein relates to a printing tabulator wh ch is adapted to be actuatedby perforated cards, which in their passage through the machine operate elements for setting up type commensurate with the designations on the card and actuate an accumulating mechanism for accumulating therein the data recorded on the card perforations whereby the total accumulated data may be computed and then printed by the printing elements of the machine.

In said co-pending application there is described a machine which comprises a main frame, a main driving shaft 2, a card feeding mechanism, a card analyzing-media nism.

Power is suitably transmitted to the cam shaft 17 provided with a plurality of cams from which are operated, as explained in said co-pending application, the various mechanisms of the tabulating machine 19, of which itsuflices here to say that these are controlled by the cards fed to the analyzer and, operate the type segments 20 so that the type 21 will be positioned to print items and totals, in accordance with the cards anthe rail supporting bar 39.

alyzed, upon a sheet of paper brought against the type by the printing carriage now to be described.

The printing carriage, designated generally by reference numeral 28 (Figs. 1, 2 and 3) is located on the rear of the printer tabulator base, to the rear of the ta ulating machine 19.

The carriage is supported, at oppos1te ends, on the cam shaft brackets 29 and the lever shaft brackets 31 carried on the base plate of the printer tabulator. These brackets are tied together at theirupper part by the tie plates'32 bolted at opposite ends to the upper part of thesebrackets respec- ,tively.

, The lever shaft brackets 31 are provided 1 at their upper ends with guide slots 34 in which are received the L shaped carriage supporting brackets 35 provided at their forward ends with anti-friction rollers 36 adapted to reciprocate in the elongated openings 37 of the cam shaft brackets.

' arms 44.

Intermediately of the ends of the supportingbar 39 are carried the forwardly projecting plates which carry at their forward ends the carriage rail 46.

The carriage proper comprises end plates 47 bracket shafts 49. On the bracket shafts are mounted the rearwardly extending supporting brackets 50 each provided with a circular opening adapted to receive the carriage rail 46, this opening being provided with arearwardly extending slot 51 adapted to provide a passage for the projecting plates 45 when the carriage is slipped on to the carriage rail. When the carriage has been put in place it is thus supported by said carriage rails and by the forward ends of the arms 44 engaging under the tie rod 48 at the lower forward part of the carriage.

Between the end plates 47 is mounted the paper roller shaft carrying part of the paper supporting and feeding mechanism to be described more in detail thereafter.

In the operation of the machine it is sometimes desirable to shift the carriage longitudinally relatively to the type sector units, so that the printed column may occupy any desired position upon the sheet of paper. Means for accomplishing this will now be described:

The forward edge of the uprights 38 (Figs. 2 and 3) of the brackets 35 are pro held spaced apart by the tie rod 48 and the T vided with inwardly turned perforated ears 61 (Fig. 5) carrying supporting studs 62 on which are slidably mounted the locating bar 64 provided with elongated slots 65 re ceiving said studs, said bar being also provided with a plurality of holes 66 large enough to receive the heads of the locating stud 67 fixedon the locating bracket 68 fixed to the shaft brackets 29 (Fig. 3) connecting the end plates 47.

The .carriage'may be swung outwardly upon the rail 46 (Fig. 3) until the stud 67 clears the holes 66 (Fig. 5) and the carriage then shifted longitudinally until the stud engages in a different hole 66, as desired. The stud 67 and bracket 68 are locked in the adjusted position by means of a locking plate 70 provided with key slots 71 each having a large end 72 through which the head of the stud 67 is adapted to pass and with small ends 74 adapted to form shoulders to engage under the heads of said studs whereby the stud is locked in position by means of a spring 75 tensioned between the upright 38 and the angular manipulating end 76 bent outwardly from said locking plate.

The locking plate 70 is held in proper position by means of the guide plates 79 and 80, the guide plate 79 being secured to one of said ears 61 and engaging over the locking plate, the guide plate 80 belng secured to the manipulating end 76 of the locking plate and provided with a slot 81 receiving a screw 82 secured to the adjacent ear 61.

The printing is accomplished by the forward movement of the paper "supporting mechanism which movement brings the paper against type 21 of the type sectors. his is accomplished by means of the upper and lower carriage actuating levers 87 and 88 (Fig. 3) pivoted on the lever shaft 89 carried by lever shaft brackets 31. The upper and lower actuating levers are both pivotally mounted on said shaft 89 and when in a printing position are locked together as will be explained, and are oscillated by means of the engagement of the cam roller 90 engaging in the cam groove 91 of the printing cam 92 carried on the cam 17. The actuating levers give one complete cycle of oscillation once for every revolution of the cam shaft 17 The locking above referred to is accomplished by means of locking cones 95 which are shown in unlocked position in Fig. 4 and must be moved to the right of said figure to lock said upper and lower levers against relative movement. These cones engage in, and when locked, hold in alinement the openings 98 and 99 of said upper and lower levers, and are carried on t e cone supporting shaft 100 yieldably drawn to unlocked position by means of the tension spring 101.

secured between the end ofsaid shaft and. a cross piece 102 (Fig. 3) disposed across the opening 104 in the lever bracket 31. The

opening 104 is large enough for the insertion of the. cone shaft and cones when assembling the machine. These cones may be moved to locking position by means of the bell crank lever 105 fulcrumed on the base of the machine and provided at its upper end with spaced ears 106 engaging a transverse pin 107 in the cone supporting shaft 100. This lever is actuated by means of a link 108 pivoted at its lower end to said lever 105 and at its upper end to the locking lever 110 (Figs. 1 and 2) fulcrumed intermediately as at 111 on the cam shaft bracket 29. The locking lever 110 terminates in a manipulating end 112 (Figs. 2 and 9) received in a slot 114 of the locking plate 115, said slotbeing provided at its upper and lower parts with shoulder forming recesses 116 and 117 in which said manipulating end may be locked to retain said locking cones in either locked or unlocked position.

Now will be described the means for supporting the paper on the carriage. On the paper roller shaft 60 journaled in the end plates 47 (Figs. 4 and 8) are disposed a plurality of paper rollers 118 each provided with a boss 119 held spaced apart by means of spacing bushings 120 7). Between adjacent pairs of the paper rollers and loosely engaging said bushings are disposed platen support brackets 121 held against rotation by means of the bracket shaft 122 passing through perforations in the lug 123 on the upper part of said brackets, said brackets being held in spaced relation by means of sleeves 124 (Fig. 8) carried on said shaft- 122. The lower part of each platen support bracket carries a forward projection 125 on which is secured as by means of a screw 126, the platen support 127 having a recess in its forward end in which is carried the elastic platen block 128 of rubber or other suitable material.

The bushings 120 hold the paper rollers out of frictional contact with the platen brackets. The bushings and the paper rollers and all the parts rotatable on the paper roller shaft 60 are caused to rotate with said shaft by means of frictional engagement with each other brought about by the clamping of the screw 129 (Fig. 3) on said shaft.

Between each adjacent pair of paper rollers are the upper and lower inner paper shields 130 and 131 (Fig. 7) which form a continuation of the cylindrical surface of the paper rollers. These shields have angular extensions .134, each extension having inwardly turned ears 135 each providedwith an openingreceivin the bracket shaft 122. The upper inner s ield 130 is pivotally supported on said rod by said ears, being permitted to move pivotally because of the rounded upper face 136, whereby access engagement of the teet may be had to the screw .126. This upper shield 130 may be omitted if desired.

Partly surrounding or housing the lower inner shields 131 and the lower part of the paper rollers 118 are the outer paper shields 137 provided withedge flanges 138 on which are formedturned ears 139 provided with openings receiving the bracket shafts 29 (Figs. 3 and 7). g I These outer shields cooperate with the lower inner shields 131 to form guides for the paper 140 on which the tabulations are to be printed, the outer shields being continued upwardly in front of the paper rollers 118, whereby are formed extensions 144 (Fig. 6) between which the type of thetype sectors pass when the paper is pressed against them by means of the platen blocks 128.

On the lower part of the flanges 138 are formed small ears 145 provided with perforations in which are carried release-arm shafts 146 (Figs. 6 and 7) on which are pivotally carried the feed roller levers 147 between the outer ends of which are journaled the paper'feed rollers 148, said roller engaging on opposite sides of the lower part of the paper rollers 118, and passing through suitable openings in the lower shields 137. These feed rollers are held in contact with the paper rollers by means of feed roller tension springs 149 secured at opposite ends to the journaled pins 150 of the rollers (Figs. 4 and 6). The inner ends of the feed roller levers are provided with inwardly pointing fingers 153 engaging over the release rod 154 guided in elongated slots 155 in the end pieces 47 (Fig. 3). When this release rod is raised the feed rollers 148 are moved to the position of the dotted lines of Fig. 6,

raising of the release rod is accomplished by I means of release arms 156 mounted on the release arm shaft 157 carried in the end plates 47 and actuated by the release lever 158 (Fig. 2) adapted to be caught behind the shoulder 159 of the inturned lug 160 on the end plate 47 to hold the rollers in released position. I

- After each number is printed by the type of the type sectors, it is necessary to feed the paper upwardly one or-more spaces. This feeding is accom lished by means of ll of the feed ratchet 161, 'mounted on the shaft 60, by a two armed feed pawl 162 (Fig. 3). pivotally mounted on the feed pawl lever 164 fulcrumed intermediately as on the stud shaft 165 and driven by the link 166, in turn driven by the drive lever 167 mounted on the feed shaft 168, said shaft being actuated by the actuating arm 169 fixed on said shaft and adapted to come into contact with and be moved by the abutment shaft 170 carried on the abutment shaft bracket 171 pivotally mounted on the tie plates 32. The brackets 171 are limited in their rearward movement by the engagement, with the tie plates 32 of a shoulder 172 formed by the lower edge of the lug 174 laterally turned at the rear edge of said abutment shaft brackets, and is yieldably held at its rearward limit of movement by a spring 175 tensioned between said lug 174 and a lug on the rear part of the shaft tie plate 32.

When the carriage is moved forwardly toward the type sectors the free end face 176 of the actuating arm 169 engage and push forwardly and rearwardly the abutment. shaft 170 against the action of the spring 175 until said end face clears said shaft and permits the shaft and its brackets to be snapped back by the spring 175 until stopped by the shoulders 172.

Fig. 3 shows the abutment shaft while being snapped back the instant after it has cleared said end face.

After the printing has taken place and the carriage moved rearwardly, the abutment shaft 170 is engaged by the lower side 173 of the actuating arm 169 whereby said arm and drive lever 167 are raised thus rocking the pawl lever 164 and lowering the pawl 162, thus turning the ratchet 161 one of more teeth depending upon how soon the lower member 177 of the pawl is permitted to engage the teeth. When it is desired that the ratchet feed only one tooth at a time, the feed limiting lever 178 pivotally mounted on the upper part of the end plate 47, is set in the position shown in Fig. 3, thus preventing the lower member 177 to continue to engage the ratchet teeth after it has moved upwardly a distance of one tooth, since the inclined inner face 179 of said member will be engaged bythe feed limiting pin 180 mounted on the lower part of the feed limiting lever.

The feed limiting lever 178 is somewhat resilient and is provided with a pair of dep'ressions 181 either one of which is adapted to be engaged by a single projection on the inner face of the end plate 47, depending upon whether the lever is shifted to the right as shown in Fig. 3, or to the left. This arrangement serves to hold the lever in shifted position.

When it is desired that the pawl feedv more than one tooth of the ratchet at a time,

the lever 178 is shifted to the left of Fig. 3

thus moving the pin 180 away from the lever pawl member 177 permitting said member to be in engagement with the ratchet teeth during the downward movement of the pawl member for adi'stance of, for instance, two teeth. If desired, the parts may be so proportioned that three or more teeth may be fed at a time.

In order to prevent the feeding of the carriage more than the desired number of teeth, as when the machine is running at very high speed, the pawl 162 is provided with an overthrow preventing cam 182 adapted to engage between the teetlrof the ratchet and the inclined face thereof, whereby the ratchet is prevented from turning another tooth space after this pawl has ceased to travel in its feeding direction. A spring 184 tensioned between the stop member 822 and the lever 804 yieldably holds the pawl in engagement-with the ratchet teeth. The feeding mechanism is yieldably held in position to feed by means of a spring 185 tensioned between the end plate "47 and a perforated ear on the upper part of the inner end of the arm 167.

In order to hold the ratchet wheel 801 and the parts carried on the shaft 60 in the positions in which they are fed by the' pawl, I provide a detent roller 186 revolubly mounted on one end of the detent lever 187 pivoted to the end plate 47 and drawn by the spring 186 strained between the other end of the detent lever and the lower part of the end plate 47 whereby said roller is yieldably yieldably holds the ratchet in the position to which it is fed.

When it is desired to insert, remove or feed the paper entirely independently of the feeding mechanism just described, I provide the mechanism, shown in Fig. 4 comprising the paper feed gear 189 fixed on the paper feed shaft 60 and engaged by the idler gear 190 rotatably mounted on the end plate 47, the idler gear being in'zturn engaged by the knob gear 191 fixed on the stud shaft 165 rotatably mounted in the end plate 47 and carrying knurled knob 192 by which said shaft and gears may be manually rotated.

lVhile the paper is being fed and during the time of printing, it is desirable that it be firmly held against the platens. This is accomplished by means of a clampin mechanism comprising a clamp bar 193( *ig. 3) carried between the outer ends of the clam ing levers 194v provided with intermediate longitudinal slots 195 loosely receiving the paper feed shaft 60, whereby the paper clamp bar is adapted to move toward and from the paper rollers as well as to revolve with said rollers. The inner ends of the clamp levers are provided with small pins 196 received in longitudinal slots 197 in the lower ends of the spring levers 198 intermedi-ately fulcrumed on the end plates 47 and drawn by a spring-199 strained between the upper end of the spring levers and the upper part of end plates 47, whereby the clamp lever 194 is yieldably drawn downwardly and the clamp bar 193 is yieldably pressed against the paper and the paper pressed against the paper rolls 118.

pressed between. the teeth of the ratchet and with the lever 194 and bar 193 and also rocks s'aid lever in a direction clockwise on Fig. 3 whereupon the bar 193 is moved downwardly over the paper and later takes a fresh grip upon the paper when the clamping lever is released by the cam on the next forward movement of the carriage and moves downwardly under the action of the spring 199.-

The upper part of the cam brackets 202 are each rovlded with an outwardly projecting ribbon feed armi 204 (Fig. 2) for operating the feed mechanism of the ribbon spools 205 carrying the ribbon 206 (Flg. 4) but as these form no part of the invention claimed herein they are not now further described.

When a total is printed it is desirable to show some. visual signal to indicate that the number printed is a total. This is accomplish-ed by shifting the carriage to the left when the total is printed, whereby the a total is shown printed a little to the right of the alinement of the listed column.

- Means for accomplishing-this result will now be described.

As shown in Fig. 4, the lower edge of the locating bar 64 is provided with a notch 240 in which engages the upper end of the vertical lever 241 pivoted intermedlately on the bracket 242 fixed on the printing lever shaft 89, the lowerend of said lever being pivotally connected to the rear end of tlIQ lIOI'I- zontal lever 244 (Fig. 2) lntermedlately pivoted on a pin 245 in a lug 246 on the base of the machine. The forward end of said horizontal lever is pivotally connected to the rear end of the totalshift lever 252.

When a total is to be taken the total pin 253 engages in the appropriate cam groove,

50 said pin is shifted to the right, and a total is set up on the type 21 all as explained in said co-pending application and the upper end of the lever 242 (Fig. 4) is shifted to the left whereupon the locating bar 64 55-is moved to the left on the pin 62 (Fig. 5)

in the slot 63, thus causing the printing to take place a slight distance to the right of the column. a

When by means of the lever 110 the car- 60 riage has been set to a non-printing position so that the items accumulated and set up by the type 2l, are not printed, it is still desirable that the totals themselves be' printed.

In order to accomplish this printing auto:

65 matically, there is provided the automatic not.

scribed, the combination of a carriage; a

println lock lever 28'! (Fig. 4) pivotallv mounte. on the bracket 258 fixed to theshaft 89, the upper end of which lever engages in a notch 260 the lower end engaging a trans verse pin 261 in the printing lock shaft 100. When the carriage is shifted to the left, the bar (34 is moved therewith and carries the upper end of the lever 257 to the left whereupon thelowe'r part of said lever saidprinti'ng lock shaft and the cones 95 are moved tot'he left thus locking together the upper and lower printing levers 87 and 88 and effecting the printing.

.From the foregoing, the operation of the printing carriage will be easily understood. Paper is inserted in the rear opening between the outer shields 137 and the inner lower paper shields 131,iand the paper rolls 118 turned by means of the knob 192 until the part on which it is desired first to print are opposite the platen blocks 128. The feed limiting lever 178 is set for the number of teeth it is desired that the feed ratchet shall be fed. If desired the locking plate 70 is unlocked and the carriage adjusted on the carriage rail and the carriage relocked.

The locking lever 110 is set in locked or unlocked position depending upon whether it is=desired that the items be printed or The tabulating machine is then started in operation as explained in the said co-pending application and the type is set and the accumulators accumulate. If the locking lever is set in locked position the cams 92 cause the printing levers and the carriage to reciprocate and the printing is effected. When a total is taken the carriage is moved to the left just before the printing by means of the total signal lever 241 engaging in the notch 240 of the locating bar. If the locking lever 110 has not been set in printing position, the automatic levers 251 also cause the cones 95 to lock the printing levers and print totals when the totals are set up and printed.
